Automated Re-Deploy of VMs using VSC cmdlets (Powershell Script)

SCOTTS2012
Currently Being Moderated

Hi,

 

Recently we had a daily powershell script that ran and re-deployed a group of servers daily. The servers were originally deployed using FlexClone and we used a Powershell script that connected to Kamino and VIServer to issue the redeploy on a scheduled task.

 

This was all working fine when we were using vCenter 4.1 and the Kamino Powershell module. However we have recently upgraded to vCenter 5.5 and now use VSC 4.2.1. According to https://communities.netapp.com/thread/25368 our old script should work with VSC with a few modifications to the Cmdlet names and importing the VSC .dll instead of Kamino.

 

However after modifying my script I can no longer connect to VSC.

 

Powershell Script: -

 

Import-Module C:\Windows\System32\WindowsPowerShell\v1.0\Modules\VSC\NetAppVSC.dll

$password = ConvertTo-SecureString -AsPlainText -Force "<password>"

$creds = New-Object System.Management.Automation.PSCredential "domain\username",$password
$controllers = New-Object com.netapp.vsc.wsapi.controllerSpec[] 1

Write-Host "Connecting to vCenter ....."
Connect-VIServer <IP Address> -User "domain\username" -Password ""

Write-Host "Connecting to VSC ...."
Connect-VSC <IP Address> -Credential $creds -Timeout 120000 -ServiceHost <IP Address>

 

 

Results of running the above is:-

 

Connecting to vCenter .....

 

Name                           Port      User                         

  ----                               ----         ----                         

<IP Address>                 443    domain\username

 

      

Connecting to VSC on Ferndownvc....

 

VCenterHostname    : <IP Address>

VCenterAddress     :  <IP Address>

VCenterCredentials : System.Net.NetworkCredential

ServiceHostname    :  <IP Address>

ServiceAddress     :   <IP Address>

VCenterVersion     :

 

Cannot tell from the above whether it has connected to vCenter and / or VSC. Previously running the above command under vCenter 4.1 and Kamino it would result in the VCenterVersion field populated as well.

 

The next line of code fails, which I think is due to not actually being connected: -

 

$targetMoref = Get-vscManagedObjectRef <datacenter name> Datacenter

Write-Host $targetMoref

 

 

Error message: -

Get-vscManagedObjectRef : The request failed with HTTP status 404: Not Found.

At C:\flexscripts\FlexRedeploy-rds_flexclone_a.ps1:19 char:39

+ $targetMoref = Get-vscManagedObjectRef <<<<  <datacenter name> Datacenter

    + CategoryInfo          : InvalidOperation: (com.netapp.vsc.vscServer:vscServer) [Get-vscManagedObjectRef], Web

   Exception

    + FullyQualifiedErrorId : ApiError,com.netapp.vsc.cmdlets.GetvscManagedObjectRef

 

I think If I can get passed this stage the rest of the script should be ok, however I have exchausted my troubleshooting to get to this stage. Are there any logs or tools I can use to troubleshoot this further, or if this is down to incorrect syntax then please advise.

 

The reason we are scrapping and rebuilding these servers on a daily basis is because they are Remote Desktop Servers. Any changes we make to a master clone, is then  re-deployed, thus not having to install new software 50+ times.

 

As previously mentioned this has been working well for months and has only broke since moving to vCenter 5.5 and VSC cmdlet module.

 

Any help on this matter would be much appreciated.

 

Regards,

 

Scott S.

    Hi Scott,

     

    I've succeeded in getting this working in my lab. Hope this helps.

      Hi Matt,

       

      Many thanks for taking the time to look at this - much appreciated. I will give this a try this afternoon but does look promising!

      Hi Matt,

       

      I have tested your script and initially it looks like it is working, however I have a couple of  anomalies : -

       

       

      • When the script runs the Write-Host output does not display the Datastore name (highlighted below in red):-

       

      Connected to VSC on IPAddress "xxx.xxx.xxx.xxx" on Port "xxxx"

      Enumerated Managed Object Reference for "testrctemplate" as "VirtualMachine:vm-2001"

      Enumerated Managed Object Reference for "" as "Datacenter:datacenter-21"

      Enumerated Managed Object Reference for "" as ""

      Enumerating files for Virtual Machine Template "VirtualMachine:vm-2001"

      Enumerating Virtual Machines deployed from Template

      "VirtualMachine:vm-2001"

      VirtualMachine:vm-2231

      VirtualMachine:vm-2230

      Initiated VSC Redeploy. VCenter TaskID "Task:task-26109"

       

      •    After running the script and returning to vSphere client I can see the task running and completing. However it never mentions "applying guest

         customization", which is crucial for the redeploy as we sysprep the VM, then run a script included in the image, which does some funky stuff;

         join domain and move to OU in Active directory, then install certificates, etc, etc.

       

        If I power on the redeployed machine the guest customization does not start, which makes me think the redploy script has not included it when

        submitting the task.

       

       

       

      I appreciate your help with this issue to date and we are practically there bar these two small issues. If I could ask for your help one last time I

      would be very grateful.

       

      Thank you

        Hi Scott,

         

        I've had a look into this for you. When using the GUI or automated methods, the vCenter task results do not mention applying guest customization for the virtual machines that have been redeployed (nor does the Kamino.log) so I wrote a script to test if applying the customization post redeploy process would work (using the vmID's returned by the VSC getVMs methods). Note that VSC and VMware return a different virtual machine ID syntax so a replace of ":" with "-" is required. See results and code below.

         

        The customization fails to apply when running the script below after a VSC redeploy (invoked either using GUI or automation).

        The error is "fault.CustomizationPending.summary" which seems to relate to:

         

        http://kb.vmware.com/kb/1006809

         

        vsc_redeploy.png

         

        Maybe due to the template being cloned with a customization in pending state. Would be interested to know if you get the same results if you run the script to apply the customization post VSC redeploy. I'm note sure why VSC isn't applying the customization (didn't work for me in the GUI either) but the script below offers a work around example to complete the process.

          Currently Being Moderated

          Hi Matt,

           

          Just a quick update to say I now have the two scripts working correctly. I have made a couple of adjustments mainly so it does not prompt for passwords (so the scripts can be scheduled to run in the early hours of the morning), instead uses a text file containing an encrypted password, this is purely to make the script a little more secure than keeping AD passwords in plain text. I also enumurate the VMs in the ApplyCustomization script instead of having to list them manually in the script.

           

          Thanks again for all yor help in finding a resolution to this issue, couldn't have done it otherwise.

           

          I have attached the final three scripts for anyone else reading this post, wishing to redeploy their VMs and apply customization. The first script (one I found on Internet) is for creating the text file that will contain the encrypted password for the Redeploy and  the ApplyCusomization scripts.

           

          Encrypt Password and save to text file script

          #STORED CREDENTIAL CODE

          $AdminName = Read-Host "Enter your Admin AD username"

          $CredsFile = "C:\usercredentials.txt"

          $FileExists = Test-Path $CredsFile

          if  ($FileExists -eq $false) {

              Write-Host 'Credential file not found. Enter your password:' -ForegroundColor Red

              Read-Host -AsSecureString | ConvertFrom-SecureString | Out-File $CredsFile

              $password = get-content $CredsFile | convertto-securestring

              $Cred = new-object -typename System.Management.Automation.PSCredential -argumentlist domain\$AdminName,$password}

          else

              {Write-Host 'Using your stored credential file' -ForegroundColor Green

              $password = get-content $CredsFile | convertto-securestring

              $Cred = new-object -typename System.Management.Automation.PSCredential -argumentlist domain\$AdminName,$password}

          #END OF STORED CREDENTIAL CODE
